AI Technical Summary
During the fuel cell stack production process, due to the poor consistency of the electrode plates stored on the tooling cart, the robot directly grabs and stacks the electrode plates, resulting in a large verticality error of the fuel cell stack, which may even exceed the outer shell size, leading to the fuel cell stack being unqualified.
An electrode plate auxiliary positioning device is adopted, including a frame, first and second positioning mechanisms. The electrode plate is precisely positioned in the horizontal direction by using a cylinder pushing component and a blocking component. The first pushing component pushes the electrode plate to the first blocking component in the first horizontal direction, and the second pushing component pushes the electrode plate to the second blocking component in the second horizontal direction, thereby achieving precise positioning of the electrode plate on the worktable.
It effectively reduces electrode plate stacking errors, improves the yield rate of fuel cell stacks, enables robots to accurately grasp electrode plates, and improves the production quality of fuel cell stacks.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A perspective view of the electrode plate auxiliary positioning device at an angle during electrode plate positioning is shown in some embodiments; Figure 2 A perspective view of the electrode plate auxiliary positioning device in some embodiments is shown from another angle when positioning the electrode plate; Figure 3 A perspective view of the electrode plate-assisted positioning device at one angle is shown in some embodiments; Figure 4Fig. 3 shows another perspective view of the electrode plate auxiliary positioning device in some embodiments. The electrode plate auxiliary positioning device provided by an embodiment of the application includes a rack 1, a first positioning mechanism, and a second positioning mechanism. The rack 1 includes a support 101 and a workbench 102, and the workbench 102 is arranged on the top of the support 101. The first positioning mechanism includes first pushing assemblies and first blocking pieces 11, which are both arranged on the workbench 102. The first pushing assemblies and the first blocking pieces 11 are spaced apart along a first horizontal direction, and the first pushing assemblies are configured to push the electrode plate 100 to the first blocking pieces 11 along the first horizontal direction. The second positioning mechanism includes second pushing assemblies and second blocking pieces 12, which are both arranged on the workbench 102. The second pushing assemblies and the second blocking pieces 12 are spaced apart along a second horizontal direction, and the second pushing assemblies are configured to push the electrode plate 100 to the second blocking pieces 12 along the second horizontal direction. The second horizontal direction is arranged at an angle with the first horizontal direction. For example, the first horizontal direction is perpendicular to the second horizontal direction, the direction indicated by the X arrow in the figure is the first horizontal direction, and the direction indicated by the Y arrow in the figure is the second horizontal direction.
[0035] In the electrode plate auxiliary positioning device, the first pushing assemblies push the electrode plate 100 to the first blocking pieces 11 along the first horizontal direction, so that the electrode plate 100 can be positioned in the first horizontal direction. The second pushing assemblies push the electrode plate 100 to the second blocking pieces 12 along the second horizontal direction, so that the electrode plate 100 can be positioned in the second horizontal direction. Through the cooperation of the first pushing assemblies, the first blocking pieces 11, the second pushing assemblies, and the second blocking pieces 12, the electrode plate 100 can be accurately positioned on the upper side of the workbench 102, so that the robot can accurately grasp the electrode plate 100, effectively reduce the error of the electrode plate 100 stack, and help improve the qualified rate of the electrode stack.
[0036] In some embodiments, referring to Figure 1 , the first pushing assembly includes a first cylinder 2 and a first pushing piece 4 connected to the piston rod of the first cylinder 2. The piston rod of the first cylinder 2 is retracted and extended to drive the first pushing piece 4 to move along the first horizontal direction, so that the first pushing piece 4 moves towards or away from the first blocking piece 11, thereby realizing positioning of the electrode plate 100 in the first horizontal direction through the cooperation of the first pushing piece 4 and the first blocking piece 11.
[0037] Continuing to refer to Figure 1 , the second pushing assembly includes a second cylinder 3 and a second pushing piece 5 connected to the piston rod of the second cylinder 3. The piston rod of the second cylinder 3 is retracted and extended to drive the second pushing piece 5 to move along the second horizontal direction, so that the second pushing piece 5 moves towards or away from the second blocking piece 12, thereby realizing positioning of the electrode plate 100 in the second horizontal direction through the cooperation of the second pushing piece 5 and the second blocking piece 12.
[0038] In order to reduce the risk of the electrode plate 100 tilting during movement, in the embodiment, referring to Figure 1 , the first pushing piece 4 comprises a first connecting plate 401 and at least two first pushing portions 402 arranged on the first connecting plate 401, the first connecting plate 401 is connected with the piston rod of the first air cylinder 2, and the at least two first pushing portions 402 are distributed along the second horizontal direction, and the first pushing portion 402 is used to contact the electrode plate 100. The second pushing piece 5 comprises a second connecting plate 501 and at least two second pushing portions 502 arranged on the second connecting plate 501, the second connecting plate 501 is connected with the piston rod of the second air cylinder 3, and the at least two second pushing portions 502 are distributed along the first horizontal direction, and the second pushing portion 502 is used to contact the electrode plate 100. At least two pushing portions are arranged on the same connecting plate, so that at least two pushing portions are driven by one air cylinder to move synchronously, thereby increasing the part of the pushing assembly in contact with the electrode plate 100, so that the electrode plate 100 is smoothly pushed, preventing the electrode plate 100 from tilting due to uneven force, and facilitating to improve the positioning accuracy of the electrode plate 100.
[0039] In the embodiment, the first pushing portion 402 and the second pushing portion 502 are both provided with two, of course, in other embodiments, the number of the first pushing portion 402 and the second pushing portion 502 can be flexibly adjusted according to needs, and the number of the first pushing portion 402 is not specifically limited, and the number of the second pushing portion 502 is not specifically limited.
[0040] In some embodiments, the first blocking piece 11 has at least two, and the at least two first blocking pieces 11 are distributed along the second horizontal direction; the second blocking piece 12 has at least two, and the at least two second blocking pieces 12 are distributed along the second horizontal direction. In this way, when the electrode plate 100 is positioned, at least two blocking pieces in the same positioning mechanism can contact the same side of the electrode plate 100 at the same time, thereby reducing the risk of the electrode plate tilting. In the embodiment, the first blocking piece 11 and the second blocking piece 12 both have two, of course, in other embodiments, the number of the first blocking piece 11 and the second blocking piece 12 can be flexibly adjusted according to needs, and the number of the first blocking piece 11 and the number of the second blocking piece 12 are not specifically limited.
[0041] In some embodiments, referring to Figure 1 , Figure 3 and Figure 4The auxiliary positioning device further comprises a first wear pad 7 and a second wear pad 8 for supporting the electrode plate 100. The first pushing part 402 comprises a first pushing block 4021 and a second pushing block 4022 connected with the first pushing block 4021. The first pushing block 4021 is arranged on the side of the first connecting plate 401 away from the first air cylinder 2, and is used to contact the side of the electrode plate 100 away from the first blocking piece 11. The second pushing block 4022 at least partially protrudes from the side of the first pushing block 4021 away from the first connecting plate 401. The top of the second pushing block 4022 is provided with the first wear pad 7, and the second wear pad 8 is arranged on the workbench 102 and located on the side of the first blocking piece 11 facing the first pushing assembly. The first blocking piece 11 at least partially protrudes from the top of the second wear pad 8. The heights of the first wear pad 7 and the second wear pad 8 protruding from the workbench 102 are equal. The first wear pad 7 and the second wear pad 8 are spaced apart along the first horizontal direction. During the extension and retraction of the piston rod of the first air cylinder 2, the first pushing block 4021 and the second pushing block 4022 are synchronously moved. Since the first wear pad 7 is arranged on the second pushing block 4022, the first wear pad 7 also moves synchronously with the first pushing block 4021. In actual implementation, when the piston rod of the first air cylinder 2 is in the retracted state, the distance between the first wear pad 7 and the second wear pad 8 in the first horizontal direction is less than the size of the electrode plate 100 to be positioned in the first horizontal direction. In this way, the electrode plate 100 to be positioned can be placed on the first wear pad 7 and the second wear pad 8, and the electrode plate 100 is supported by the first wear pad 7 and the second wear pad 8. The extension of the piston rod of the first air cylinder 2 can drive the first pushing block 4021, the second pushing block 4022, the first wear pad 7 and the electrode plate 100 to move towards the first blocking piece 11. With the extension of the piston rod, the electrode plate 100 is finally positioned in the first horizontal direction by being closely fitted to the first pushing block 4021 and the first blocking piece 11 respectively on the opposite sides in the first horizontal direction. It can be understood that during the pushing of the electrode plate 100 in the first horizontal direction, the electrode plate 100 moves relative to the second pushing block 4022 and the workbench 102 respectively. The arrangement of the first wear pad 7 on the second pushing block 4022 and the second wear pad 8 on the workbench 102 can avoid the wear of the first positioning mechanism and the workbench 102 by the electrode plate 100.
[0042] In this embodiment, continuing to refer to Figure 1 、 Figure 3 and Figure 4The auxiliary positioning device further comprises a third wear-resistant pad 9 and a fourth wear-resistant pad 10, which are used to support the electrode plate 100. The third wear-resistant pad 9 is spaced apart from the second pushing assembly along the second horizontal direction, and the third wear-resistant pad 9 is located on the side of the second blocking piece 12 facing the second pushing assembly, and the second blocking piece 12 at least partially protrudes from the top of the third wear-resistant pad 9. The second pushing part 502 comprises a third pushing block 5021 and a fourth pushing block 5022 connected with the third pushing block 5021. The third pushing block 5021 is arranged on the side of the second connecting plate 501 away from the second air cylinder 3, and the third pushing block 5021 is used to contact the side of the electrode plate 100 away from the second blocking piece 12. The fourth pushing block 5022 at least partially protrudes from the side of the third pushing block 5021 away from the second connecting plate 501, and the top of the fourth pushing block 5022 is provided with the fourth wear-resistant pad 10. The third wear-resistant pad 9 and the fourth wear-resistant pad 10 protrude from the workbench 102 by the same height, so that the third wear-resistant pad 9 and the fourth wear-resistant pad 10 can jointly contact the bottom of the electrode plate 100, thereby supporting the electrode plate 100. In the embodiment, the first wear-resistant pad 7, the second wear-resistant pad 8, the third wear-resistant pad 9 and the fourth wear-resistant pad 10 protrude from the workbench 102 by the same height. During the process that the second pushing assembly pushes the electrode plate 100 along the second horizontal direction, the electrode plate 100 can move relative to the fourth pushing block 5022 and the workbench 102. The third wear-resistant pad 9 arranged on the fourth pushing block 5022 and the fourth wear-resistant pad 10 arranged on the workbench 102 can reduce the wear of the electrode plate 100 on the second pushing part 502 and the workbench 102, which is conducive to prolonging the service life of the auxiliary positioning device. The third pushing block 5021 and the second blocking piece 12 contact the two sides of the electrode plate 100 in the second horizontal direction respectively, so as to realize the accurate positioning of the electrode plate 100 in the second horizontal direction.
[0043] In order to facilitate the control of the first air cylinder 2 and the second air cylinder 3, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The auxiliary positioning device further comprises a controller 14 located below the workbench 102. The controller 14 is installed on the support 101, and the controller 14 is used to control the actions of the first air cylinder 2 and the second air cylinder 3. Installing the controller 14 on the support 101 can make full use of the space on the support 101, which is conducive to optimizing the structure of the auxiliary positioning device.
[0044] In some embodiments, refer to Figure 3 and Figure 4The auxiliary positioning device further comprises a sensor 13 connected in communication with the controller 14, the sensor 13 is arranged on the workbench 102, and the sensor 13 is used to sense the electrode plate 100. In actual implementation, when the sensor 13 senses the electrode plate 100, the sensor 13 transmits a signal to the controller 14, and the controller 14 controls the first cylinder 2 and the second cylinder 3 to act. In the embodiment, the sensor 13 is a proximity switch, and of course, in other embodiments, the sensor 13 can also be other types of sensor devices.
[0045] In order to enable the auxiliary positioning device to position electrode plates 100 of different sizes, in the embodiment, the first cylinder 2 is an adjustable-stroke cylinder, and the second cylinder 3 is an adjustable-stroke cylinder, so that the stroke of the cylinder can be adjusted according to the size of the electrode plate 100, thereby enabling the auxiliary positioning device to position electrode plates 100 of different sizes and improving the applicability of the auxiliary positioning device. Of course, in other embodiments, only the first cylinder 2 can be an adjustable-stroke cylinder, or only the second cylinder 3 can be an adjustable-stroke cylinder.
[0046] In some embodiments, referring to Figure 2 and Figure 5 The auxiliary positioning device further comprises at least two sets of guide assemblies 6, and each of the first pushing assembly and the second pushing assembly corresponds to a guide assembly 6. The guide assembly 6 comprises a limiting block 601 and a guide piece 602. The limiting block 601 is fixed on the workbench 102, and the limiting block 601 is provided with a limiting hole 603. The guide piece 602 is slidingly arranged in the limiting hole 603, and one end of the guide piece 602 is connected with the first pushing piece of the first pushing assembly or the second pushing piece of the second pushing assembly, that is, the first pushing piece 4 is connected with one end of the guide piece 602 in the corresponding guide assembly 6, and the second pushing piece 5 is connected with one end of the guide piece in the corresponding guide assembly 6. In the embodiment, the auxiliary positioning device comprises two sets of guide assemblies 6, and the first pushing assembly and the second pushing assembly correspond to the two sets of guide assemblies 6 one by one. It can be understood that the pushing part of the pushing assembly drives the guide piece 602 to slide in the limiting hole 603 during movement, and through the sliding cooperation of the guide piece 602 and the limiting hole 603, the moving direction of the pushing part can be prevented from deviating, which is beneficial to accurately positioning the electrode plate 100 by the auxiliary positioning device. Exemplarily, in the guide assembly 6 corresponding to the first pushing assembly, the guide piece is connected with the first connecting plate 401 in the first pushing piece 4; and in the guide assembly 6 corresponding to the second pushing assembly, the guide piece is connected with the second connecting plate 501 in the second pushing piece 5.
[0047] The working process of the auxiliary positioning device is described in detail as follows:
[0048] Step S1, the robot picks up the electrode plate 100 from the tool car and places it on the first wear-resistant pad 7 and the second wear-resistant pad 8 above the workbench 102;
[0049] Step S2, after the sensor 13 senses the electrode plate 100, the first cylinder 2 is controlled to act by the controller 14;
[0050] Step S3, the piston rod of the first cylinder 2 is elongated and drives the first push block 4021 and the second push block 4022 to move towards the first blocking piece 11, so that the electrode plate 100 moves towards the first blocking piece 11, when the electrode plate 100 is close to the first blocking piece 11 on the side away from the first cylinder 2, the positioning of the electrode plate 100 in the first horizontal direction is realized, and the piston rod of the first cylinder 2 is reset;
[0051] Step S4, the controller 14 controls the piston rod of the second cylinder 3 to be elongated, and pushes the electrode plate 100 towards the second blocking piece 12, when the electrode plate 100 is close to the second blocking piece 12 on the side away from the second cylinder 3, the positioning of the electrode plate 100 in the second horizontal direction is realized, and the piston rod of the second cylinder 3 is reset.
[0052] The above-mentioned auxiliary positioning device can position the electrode plate 100 in the first horizontal direction and the second horizontal direction respectively, so that the robot can accurately grasp the electrode plate 100, and prepare for the automatic stacking of the electrode stack.
[0053] It should be noted that the auxiliary positioning device can be applied to the auxiliary positioning of the electrode plate of the flow battery, and can also be used for the auxiliary positioning of the electrode plate of other batteries.
[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily, in order to make the description simple, not all possible combinations of the technical features in the above-mentioned embodiments are described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.
[0055] The above-mentioned embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the patent application scope. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
